When I replaced the furler on my boat about 6 years ago, I did a lot research and spoke to a lot of other sailing friends about their experiences. I chose a Furlex 200 as I believed it to be the highest quality -- and perhaps highest price. (Note: Practical Sailor tends to rate all the major furlers as pretty much equal in quality).
Since that time, I would say that I am generally satisfied with the Furlex, but not overjoyed. While the quality and workmanship of the systems components is good, I have sometimes found it hard to reef a big genny in a blow when sailing solo. You seem to need 3 hands at such times. (I admit to being a late reefer). I now compensate by blanketing the headsail with the main when I need to reef or furl the headsail, whenever circumstances allow.
While I originally thought the enclosed drum of the Furlex would be a plus, I no longer think it is. In my early years with the Furlex, I had a few line jams mostly due to not keeping adequate pressure on the furling line when initially unfurling the sail. This allowed line to pile up on the drum and overlap. I do not believe other quality furlers require such care when unfurling but that view is anecdotal. I have found that line jams are difficult to clear with an enclosed drum. I have virtually eliminated the potentail for jams (at least I hope so) by moving the first deck fairlead forward to change the angle of the furling line as it exits the drum and using a ratchet block on the last fairlead aft before the furling line is cleated.
In sum, if and when I replace the Furlex, I would not buy Furlex again.
